[Varicocele in children and adolescents. Review of a series of 58 cases].

5 to 25% of male adolescents present with a varicocele; only those cases inducing serious discomfort or affecting the development of the testis require surgical treatment. Nevertheless, the results of surgery are disappointing, with a high recurrence rate. Based on a better knowledge of testicular venous drainage, it appears that conventional high ligation of the spermatic vein (s) might not be sufficient to cure varicocele. Fifty-eight patients were operated upon using four different procedures. Only complete, proximal ligation of all of the visibly dilated veins seems to prevent recurrences with a follow-up of at least one year. However, out of eleven cases treated with this original procedure, one patient, already operated upon twice without success, developed secondary atrophy.

Spontaneous hematoma of the kidney simulating a nephroblastoma. Report of two cases.

The International Society of Pediatric Oncology (SIOP) 6 clinical trial for Wilms' tumor (WT) includes preoperative chemotherapy for all nonmetastatic patients. Approximately 50% of patients treated in this manner can be classed stage 1 after surgery. This strategy requires a positive diagnosis in the absence of histologic data. Diagnostic errors are very rare: Only 1.5% of the first 856 cases entered in the SIOP 6 trial were found to be benign. This article reports two very similar cases of spontaneous hematoma of the kidney that were initially misdiagnosed as hemorrhagic WT. Unusual severe acute anemia was a feature of both cases. Even the most modern state-of-the-art imaging techniques were unable to rule out the possibility of a tumor subjacent to a voluminous renal hematoma. The patients' courses during preoperative chemotherapy were of no formal diagnostic value, and the correct diagnosis was not made until surgery.

[Transureteroureterostomy. Results in a series of 42 children and young adults].

Forty two TUU have been performed from 1974 to 1986 in children and young adults: the youngest was 10 years, the oldest 26. The mean follow-up has been more than 5 years: 23 bladder exstrophies, 12 neurogenic bladders, 5 mega-ureters and 2 retroperitoneal tumors. TUU were performed after failure of uretero-cysto-neostomies (8/42) ou uretero-sigmoid reimplantation (19/42). The technique with details about drainage (16/42) is described. In 5 cases, complications appeared early: 3 fistulae, 2 sweelings of the anastomosis. tests done 3 months after the operation did not show any other complication in relation with the TUU. Nevertheless one reflux and 3 stenoses of the end of the recipient ureter caused dilatation of two upper urinary tracts. During the long term follow-up, it was necessary to perform 2 nephrectomies of the donor ureter and 5 operations on the end of the recipient ureter. These complications were independant of the TUU. The final result of TUU was excellent.

[Ureteral reimplantation using the psoas bladder hitch. Apropos of 42 cases].

42 cases of ureterocystoneostomy with psoas hitch were performed: 22 boys, 20 girls. The majority of the cases were done between ages 4 and 6. Initially 8 cases presented with reflux, 9 with megaureter and reflux, 20 with megaureter without reflux, 5 cases of ureterocele with duplication. 2 cases were done as a primary procedure, 4 cases as a part of undiversion, 36 after failure of a reimplantation either for reflux (13) or for stenosis (23). The technique is described: four cases were done bilaterally. Another procedure accompanied the psoas hitch: 20 ureteral modelage, 3 transuretero-ureterostomies. Follow up varied from 1 to 13 years with good results in 27 cases, fair results in 10 and poor results in 5.

[The valves of the posterior urethra].

75 cases of posterior urethra valves have been seen and treated from 1952 to 1984. The average follow-up is 11 years. The clinical symptomatology is described and the different treatments are analyzed from a critical point of view. A the present time the progress made by pediatric intensive care, minimization of endoscopes, better understanding of lesions, indicate that the only treatment has to be the valves. A urinary diversion is to be considered only if the life of the boy is in danger. It is rare to have to reimplant the ureters. 3 boys died. From the cases with long follow-up, 4 have high blood pressure, 16 have renal insufficiency, of these one had a successful renal transplant, 6 are dialyzed. The problems of urinary continence and fertility are discussed.

[Polyp of the posterior urethra. Apropos of 6 cases].

Polyp of posterior urethra is a rare cause of urinary obstruction. Attached by a pedicle to the superior part of the veru montanum, such a polyp is mobile and can move in the bulbar urethra, causing urinary retention. If can also bleed provoking either hematuria or urethrorrhagia. Urinary infection can be present. Vesico-urethral ultrasound examination can show the polyp. But the diagnosis is made on a voiding cystourethrogram either at the end of an intravenous pyelogram or after suprapubic puncture of the bladder. Cystourethroscopy can also diagnose the lesion, and can treat it by electrocoagulation of the pedicle. Surgery by suprapubic incision and cystostomy is another method of treatment. It is perhaps less dangerous that the endoscopic treatment because the pedicle is very close to the ejaculatory ducts. Pathology of polyp of posterior urethra is variable but benign. The most frequent lesion is a fibrous polyp specially in children. Recurrency of such a lesion is very exceptional.

[Vulvar cysts disclosed in a neonate. Apropos of 6 cases].

The authors report six cases of vulvar cysts in female neonates. Careful examination of the vulva normally leads to correct diagnosis of this rare lesion, but a few additional examinations may be helpful. Simple puncture without anesthesia is generally sufficient for a successful treatment of this benign and isolated tumor. The authors go on to discuss the embryological, histological and histochemical aspects, and review the literature.

[Pyelo-ureteral duplication and vesico-ureteral reflux].

106 children (76 girls and 30 boys) were treated for vesico-ureteric reflux in double upper urinary tracts. The results of different treatment protocols are discussed. Medical treatment is rarely successful. Partial or total nephrectomy is sometimes necessary because of very poor renal function. Cohen's technique for the "en bloc" ureterocystoneostomy of the two ureters seems to provide the best conservative treatment. But the results, which are good as far as the reflux is concerned, are often unsatisfactory because of the scarring of the renal parenchyma, especially as regards the inferior pole, and because of persistent urinary infection.

[A series of 34 cases of prune belly syndrome in children].

The congenital triad of abdominal muscle deficiency, urinary tract anomalies and cryptorchidism is often called prune-belly syndrome because of the wrinkled abdominal skin of these neonates. Other associated anomalies may be noted, such as cardiovascular, gastrointestinal or orthopedic disorders. The incidence is about 1 in 40 000 births. Prune-belly is in fact a spectrum of diseases falling into three main groups with very different prognoses and treatments. In group 1, the severe urinary and pulmonary abnormalities usually lead to stillbirth or death in infancy, and need no surgical management. In group 2, the mean survival rate is high (83%), and surgery may be required in some cases, mainly for urinary diversion. In group 3, the disorders are very mild, and the children are often called "pseudo-prunes". The etiology is unknown, but the syndrome appears to be due to arrested mesenchymal development between the sixth and tenth weeks of gestation. In groups 2 and 3, the main problems are to ensure sterility of the urine by close supervision, and to prevent the severe accidents which may be caused by retrograde radiological exploration. A more conservative approach to the syndrome appears to improve the prognosis, and the spontaneous improvement of big megaureters without infectious complications would seem to favor this line or argument.
